Just replaced ignition lock cylinder, now had electrical issues

I just replaced a broken ignition lock cylinder on my 2001 A6 2.7t. I replaced all the wires correctly, but when I turned the car on, the Air Bag, ABS, Traction control, and brake light all came on. These were not on when I had the ignition lock failure. Also, the horn does not work and the automatic windows do not move up and down with one click. Any suggestions? I think the computer may need resetting.
